- assert if {isc,dns,ns}_test_begin() is called when a prior test is running
- add dns_test_init() and dns_test_final(), which can be run before and
after all tests. this ensures openssl doesn't have to be reinitialized.
The ATOMIC_*_LOCK_FREE can evalutate either 0, 1, or 2 which indicate the
lock-free property of the corresponding atomic types (both signed and unsigned).
Value Explanation
----- --------------------------------------
0 The atomic type is never lock-free
1 The atomic type is sometimes lock-free
2 The atomic type is always lock-free

Utimaco HSM requires user to be logged in before executing DigestUpdate, thus
breaking dst_lib_init2 that ran isc_md5_check and isc_sha1_check before sending
PIN to the HSM. Therefore isc_*_check needs to be disabled when Utimaco HSM is
being used as PKCS#11 library.
While implementing the new unit testing framework cmocka, it was found that the
BIND 9 code doesn't compile when assertions are disabled or replaced with any
function (such as mock_assert() from cmocka unit testing framework) that's not
directly recognized as assertion by the compiler.
This made the compiler to complain about blocks of code that was recognized as
unreachable before, but now it isn't.
The changes in this commit include:
* assigns default values to couple of local variables,
* moves some return statements around INSIST assertions,
* adds __builtin_unreachable(); annotations after some INSIST assertions,
* fixes one broken assertion (= instead of ==)

While isc_buffer_copyregion() calls isc_buffer_reserve() to ensure the
target buffer will have enough available space to append the contents of
the source region to it, the variables used for subsequently checking
available space are not updated accordingly after that call. This
prevents isc_buffer_copyregion() from working as expected for
auto-reallocated buffers: ISC_R_NOSPACE will be returned if enough space
is not already available in the target buffer before it is reallocated.
Fix by calling isc_buffer_used() and isc_buffer_availablelength()
directly instead of assigning their return values to local variables.
(cherry picked from commit e1f0aed034)
Add some basic checks for isc_buffer_copyregion() to ensure it behaves
as expected for both fixed-size buffers and buffers which can be
automatically reallocated. Adjust the list of headers included by
lib/isc/tests/buffer_test.c so that it matches what that test program
really uses.
